The final novel in the METAMORPHOSIS trilogy!

Now in command of a massive daemonic army, Yaghur Hod invades the Abyss and seeks to reclaim the portion of his power still trapped within the sentient sword, Fiendbleeder. But the mighty daemon's allies include more than the teeming multitudes of Hades and Gehenna - he has awakened an ancient and terrible evil from an eons-long sleep, promising the souls of all who stand against him to the eldritch horror.

As Yaghur Hod battles his way through the realms of Abyssal lords foolish enough to oppose him, Hazergal and a motley alliance of archfiends race to gather an army of their own.  In the face of this dire threat, the former archmage must hold together a tumultuous alliance of fiends, while struggling to retain his humanity in an ever-changing demonic body.

And, as Yahgur Hod and his army close in, Hazergal is forced to make a blasphemous choice: ascend to the pinnacle of demonic power and sacrifice what is left of his humanity or face utter destruction.
